Going to bed for a 5:57 am alarm

Asleep by 8:42 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:12 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:42 pm — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

Online alarm clock for 5:57 am

You are only just waking at 5:57 am, with the chickens still waiting to be let into the yard after dawn. An alarm now gives you a moment to get your bearings, pull on something warm and be ready to open the coop around 6:00 am, rather than rushing outside half awake.

For this early start, choose the alarm sound to suit how easily you wake and who else is within earshot. A softer tone can ease you awake without startling the household, while a more persistent sound makes sense if you often drift off again. Set the volume before settling down and leave the browser running overnight. If the browser closes or the computer goes to sleep, the alarm will not sound, so the chickens could remain shut in beyond the time you intended.

Before bed, place the screen where you can reach it without holding a bright display close to your eyes at 5:57 am. Lower the brightness in advance and use a warm display setting if your phone or computer provides one. When the alarm sounds, silence it with a quick tap, let your eyes adjust to the early light, then check the path to the coop before stepping outside.

Common questions

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 5:57 am?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
